Hold a wakelock during backup/restore/clear operations
We need to make sure we stay alive for the duration of a backup or (especially)
restore operation. The existing Handler-based timing system was simply not
properly functional, so it's been retooled to use a repeating alarm delivering a
broastcast PendingIntent to our registered receiver.
We acquire a partial wake lock in the broadcast receiver [i.e. while the Alarm
Manager is holding one for the duration of broadcast delivery] and pass the
wakelock object to the backup thread, which eventually releases it when it's
finsihed operations. A similar pattern is used for the threads handling restore
and clear.
